Definitions

  • the invention relates to a generator connection of a photovoltaic system.
  • Photovoltaic surface elements or photovoltaic modules of photovoltaic systems supply the electricity they generate via respective so-called stranded conductors.
  • the strand lines of the individual photovoltaic surface elements are usually combined in standard systems, ie systems both small and large power by means of so-called generator connections or generator junction boxes to a derivative.
  • the lead is followed by a photovoltaic inverter.
  • the photovoltaic inverter feeds the electricity generated by the photovoltaic system into a power grid, for example the public power grid.
  • the generator terminals thus serve as means for collecting the individual strand lines and act on the one hand as protection for the photovoltaic inverter and on the other hand for the photovoltaic surface elements (DC or DC side) against overcurrent coupling via solar connection cables. Furthermore, they form a DC separation point between the photovoltaic inverter and the photovoltaic surface elements. This function is mandatory according to IEC 60364-7-712. If required, the generator connections also serve to accommodate string diodes or string fuses.
  • the generator terminals of today's photovoltaic systems therefore represent complex circuit arrangements with a variety of functions, which are usually realized depending on the nature and performance of the associated photovoltaic system by wiring individual components together.
  • the components are to be attached and wired individually in associated control boxes, which can only be done by professionals.
  • the wiring is not only expensive but also carries a high risk of error.
  • a generator connection of a photovoltaic system is provided with at least two supply terminals, at least two return current diodes and a discharge terminal, in which the supply terminals, the return current diodes and the discharge terminal arranged on a printed circuit board, each lead terminal electrically connected to an associated reverse current diode and the return diodes are electrically connected by means of a manifold formed on the printed circuit board to the drainage terminal.
  • the circuit board is a printed circuit board with it equipped lead terminals, reverse current diodes and drainage terminal.
  • the printed circuit board is preferably a printed circuit board with reverse current diodes soldered onto it.
  • a measuring point it is also preferable for a measuring point to be arranged in an electrically conductive manner between at least one of the supply terminals and the associated return current diode.
  • the components provided in the generator connection according to the invention of a photovoltaic system, supply terminals, return diodes and discharge terminal are advantageously designed according to the inventive solution as surface-mounted components, which are arranged on a circuit board and combined in this way to form an assembly.
  • a collecting line is also formed, which establishes the electrical connection between the return current diodes and the discharge terminal.
  • Such an assembly according to the invention not only has the advantage that it as such is smaller than previously known (wired from individual components) assemblies, but also represents a tested design with less error rate and overall higher quality due to the possibility of prefabrication of the assembly according to the invention.
  • the measurement points advantageously provided according to the invention enable a further simplified error analysis and, if desired, simple evaluation of the individual currents delivered by the photovoltaic surface elements.
  • FIG. 1 shows a perspective view of a generator connection according to the invention of a photovoltaic system.
  • a generator terminal 10 of a further not illustrated photovoltaic system is shown, in which on the upper side of a plate-shaped printed circuit board 12 six lead terminals 14 are fixedly mounted.
  • the supply terminals 14 are individually designed disk-shaped and arranged side by side with each other and juxtaposed with their large-area sides that a sequence arises.
  • a single strand line 16 is electrically connected, which leads to an associated (not shown here) photovoltaic surface element of the associated photovoltaic system.
  • photovoltaic surface element irradiated solar energy is converted into electrical energy in the form of an electrical voltage or an electric current.
  • associated measuring points 18 with integrated separating point 20 for the possible separation of the electrical connection for measuring purposes are arranged directly behind each of the supply terminals 14.
  • the measuring points 18 are each individually electrically conductive via an associated, on the Underside of the printed circuit board 12 formed (and not visible in the illustrated perspective view) trace connected to the associated lead terminal 14.
  • an associated reverse current diode 22 is arranged on the upper side of the printed circuit board 12 in each case.
  • the return current diodes 22 each have a first, input-side contact point 24 and a second, output-side contact point 26, of which in each case the first contact point 24 individually electrically conductive via an associated, likewise formed on the underside of the printed circuit board 12 (and not in the illustrated perspective view visible) conductor track with the associated measuring point 18 is connected.
  • each of the return current diodes 22 are each connected to a likewise formed on the underside of the printed circuit board 12 (and in the illustrated perspective view only shown in pencil) conductor, which is electrically connected to a drainage terminal 30 as a manifold 28.
  • the drainage terminal 30 is arranged in the front region of the printed circuit board 12 at its upper side next to the row of supply terminals 14.
  • a derivative 32 is electrically connected, which leads to a (not shown) photovoltaic inverter of the associated photovoltaic system.
  • the supply terminals 14, the measuring points 18 with integrated separation point 20, the return current diodes 22 and the drainage terminal 30 are all soldered as components on the circuit board 12.
  • the electrical connections to the said interconnects, in particular the manifold 28, are also produced by means of soldering.
